Explain conservation of charges and find final charges on each square plate (first one has side 1 cm and -5 charge the second one has side 2 cm and +15 charge) when they are touched each other. help (;´༎ຶٹ༎ຶ`)

The final charge on each square plate is +10

Explanation:

The law of conservation of charge states that the charge in a system, isolated from the environment, can only be transferred to another system, as the charges can neither be destroyed nor created

Therefore, the sum of the charges in a system is always constant such that the net charge in the universe is constant

Therefore, given the amount of charges in the 1 cm side = -5

The amount of charge in the 2 cm side = +15

The net charge when they touch = The charge on the 1 cm + The charge on the 2 cm

The net charge when they touch = -5 + 15 = +10

The final charge on each square plate = +10.

i would think klcio3

we need to know the time interval during which the force acts. impulse of force = momentum change
